提示词

Create a premium cinematic square editorial photograph. Scene: a vast, symmetrical flooded travertine hall with monumental pale stone columns, repeating skylights, and a mirror-like layer of shallow water across the floor. Subject: one elegant European woman in an indigo and seafoam silk couture gown, centered in the architecture. She is captured mid-turn with a calm, commanding expression. The translucent fabric expands into a dramatic circular arc, with physically believable water splashes tracing the outer edges of the moving dress. Her face remains sharp and recognizable while the fabric conveys motion. Composition and lighting: 1:1 square, full-body fashion portrait, rigorous central symmetry, strong architectural depth, controlled cool daylight from the ceiling, realistic reflections, crisp fabric detail, natural skin texture, restrained indigo, seafoam and travertine palette. Aesthetic: high-fashion European campaign photography, sophisticated, cinematic, photorealistic and richly art-directed. Constraints: one European woman only; no Asian person or East Asian motifs; no text, logo, watermark, border or UI; no extra limbs, distorted hands, duplicated body parts, fantasy creatures, illustration or cartoon appearance.

提示词

Create a square 1:1 bright, clean, ultra-photorealistic winter wildlife photograph based on the concept “Snow Duck,” using an eye-level slight close-up, soft winter daylight, cool pastel color, a snowy field background, and the subject's upper body supported on the snow while leaning forward. Primary subject: one small fluffy white domestic duck with immaculate soft feathers, a natural tangerine-orange beak, clear dark eyes and pale orange webbed feet. The duck is sliding gently forward through deep powder snow with its chest and upper body supported on the snow surface, torso leaning forward, neck slightly extended and wings held just a little away from the body for balance. Its expression should feel naturally alert and charming, never cartoonish. Environment: an expansive pristine alpine snowfield under a luminous pale-blue morning sky. Low rounded snowdrifts create soft layers into the distance. Frosted European silver birch trees stand far in the background, with muted lavender-blue mountain shapes barely visible through bright atmospheric haze. Tiny airborne ice crystals sparkle in sunlight. A shallow curved trail behind the duck shows where it has slid through the powder. Visual accents: place several small translucent frozen bubbles in the snow around the duck, catching restrained rainbow refractions and soft peach, mint and sky-blue highlights. Add delicate frost crystals to the tips of the duck's breast feathers and fine snow powder lifting beside its wings. Keep the scene uncluttered and premium. Composition and lighting: square frame, camera at the duck's eye level only a few centimeters above the snow, subject slightly below center, clean open sky and snow as bright negative space, shallow depth of field, high-key diffused winter daylight and a soft warm sunrise rim from the left. Retain full snow and feather detail. Constraints: exactly one real duck; no humans or other animals; no clothing or accessories on the duck; no Asian or East Asian motifs; no dark fantasy, night scene, black background, heavy shadows or gloomy atmosphere; no readable text, logo, watermark, border or UI; no extra wings, legs, beaks or eyes; no plush toy, illustration, cartoon or plastic CGI appearance.

提示词

Create a square 1:1 surreal cinematic film still featuring exactly a sloth, a tuna and an F-15E aircraft, photographed in the visual character of a richly preserved 1970s Eastman Color motion picture. Scene: a rain-soaked coastal European airbase at dawn after a storm. A real three-toed sloth wearing a tiny weathered olive flight jacket sits calmly on top of an enormous silvery bluefin tuna resting on a low yellow aircraft-maintenance trolley. Behind them, a full-scale F-15E is parked diagonally on the wet runway beneath towering orange-gray clouds, its canopy closed and engines off. The combination should feel intentionally absurd yet staged with complete photographic seriousness, like a lost frame from an expensive surreal adventure film. Action and atmosphere: the sloth raises one paw as if directing ground operations; the tuna's wet scales catch the runway lights; wind moves loose straps and puddle surfaces. A small flock of seabirds crosses the distant sky. No people are present. Composition: square cinematic frame, low camera near runway level, sloth and tuna dominant in the foreground, F-15E forming a powerful diagonal in the middle ground, distant sea wall and storm clouds creating layered depth. Eastman Color treatment: saturated but slightly faded cyan shadows, warm amber highlights, dense reds, gentle halation around runway lamps, organic 35mm grain, subtle gate weave and period-accurate contrast. Photorealistic practical-effects surrealism with detailed fur, fish scales, wet concrete and aircraft metal. Constraints: exactly one sloth, one tuna and one F-15E; no pilot or ground crew; no weapon firing, explosion, combat or damage; no readable aircraft markings, numbers, flags, text, logo, watermark, border or UI; no East Asian motifs; no anthropomorphic human face; no illustration, animation or plastic CGI appearance.

提示词

Create a photorealistic 16:9 reference portrait for use as the identity source of a miniature product scene. Subject: one European man in his early thirties with fair neutral skin, a softly angular face, expressive hazel eyes, fluffy curly auburn-brown hair, thick natural eyebrows and a neatly trimmed short beard. He has a warm, quietly confident expression with a subtle closed-mouth smile. Pose and framing: medium seated portrait from the waist up, body turned slightly three-quarters toward camera, shoulders relaxed, one forearm resting naturally on a walnut desk, direct eye contact. Place him slightly left of center while keeping his face large and clear. Wardrobe: faded charcoal crew-neck T-shirt, relaxed dark trousers partly visible, clean off-white sneakers suggested beneath the desk, no branding or printed graphics. Matte-black wireless headphones rest loosely around his neck. Environment: a refined contemporary music studio with warm walnut surfaces, a small record player, blank record sleeves with no readable text, one sculptural table lamp, a compact green plant and softly blurred acoustic panels. Lighting and style: warm late-afternoon window light mixed with a soft tungsten practical lamp, cinematic shallow depth of field, realistic shadows, premium lifestyle photography, high micro-detail in face, hair, fabric and wood. Constraints: one European man only; no Asian person or East Asian motifs; no text, letters, brand marks, logo, watermark, border or UI; no distorted hands, extra limbs, exaggerated cartoon proportions or illustration appearance.

提示词

Use the supplied image as the exact facial and identity reference for a playful premium miniature-product photograph. Recreate the same European man with the exact recognizable face, hazel eyes, fluffy curly auburn-brown hair, eyebrows, beard shape, fair neutral skin and subtle confident smile. On the same warm walnut studio desk, place a large open premium off-white wireless-earbuds charging case as the central hero product. Inside the case sits a tiny stylized miniature version of the referenced man, comfortably occupying the molded interior as if it were a lounge chair. He leans one arm naturally on the curved rim, keeps one knee raised and relaxes the other leg over the edge while looking toward camera. His face, hair and beard must remain photorealistic and identifiable. Preserve the faded charcoal T-shirt, relaxed dark trousers, clean off-white sneakers and matte-black headphones around his neck at miniature scale. Place two full-size off-white wireless earbuds in the foreground with realistic glossy reflections. Add a modern smartphone standing vertically behind the case and showing an abstract dark music visualizer made only from colored wave shapes and playback symbols, with no words or letters. Include one blank record sleeve, a small green plant, the cream dome lamp and softly blurred acoustic panels. Use a cinematic 16:9 product hero composition with the charging case centered slightly right, the miniature character as focal point, earbuds creating foreground depth, and the phone and studio objects creating layered background depth. Use cozy tungsten light mixed with late-afternoon window light and physically believable plastic, metal, fabric, skin and walnut reflections. Constraints: same European male identity only; no Asian person or East Asian motifs; no second human; no brand, logo, readable text, letters, watermark, border or UI frame; no distorted face, hands, extra limbs or duplicate character; no oversized human outside the case; no low-detail toy face; no illustration or flat cartoon rendering.

提示词

Create a cinematic 16:9 reference photograph with a distinctive full-body pose for a later character-replacement edit. Subject: one European male wilderness guide in his mid-thirties with fair weathered skin, short dark-blond hair and a neat beard. He wears a mustard-yellow technical parka, charcoal hiking trousers, brown leather hiking boots, a dark forest-green backpack and rust-colored knit gloves. No visible branding. Action and pose: he balances mid-step on a wide moss-covered fallen tree trunk. His left boot is planted near the center of the log; his right leg extends behind him with the heel lifted. His torso leans slightly forward. His left arm reaches outward and slightly upward for balance with an open gloved hand; his right elbow is bent close to the torso while his right hand holds a small bright-red metal thermos upright at chest height. His head turns toward camera with an amused, focused expression. The entire body, both hands, both boots, thermos and backpack are visible. Environment: a richly detailed late-autumn European beech forest after rain, with amber leaves, moss, ferns, shallow mist between tree trunks, wet bark, small reflective puddles and soft distant hills. The fallen log crosses diagonally from lower left toward center. Composition and lighting: landscape 16:9, full-body environmental photograph, slightly low eye-level angle, subject left of center, 35mm lens, strong foreground-to-background depth, cool overcast daylight with one soft warm shaft through the canopy. Constraints: one European man only; no Asian person or East Asian motifs; no animals; no snow; no readable text, logo, watermark, border or UI; no extra limbs, fused fingers, hidden feet, distorted thermos, illustration or CGI appearance.

提示词

Use the supplied image as an exact reference for framing, pose, object placement and camera distance. Preserve the exact 16:9 crop, camera angle, focal length, subject scale and left-of-center placement; the same diagonal fallen log; planted front foot; lifted rear leg; forward torso lean; extended left arm; bent right elbow; upright red thermos; backpack position; head direction; and open forest space on the right. Replace the European male hiker completely with one friendly, photorealistic white fluffy bear standing anthropomorphically in the identical balancing pose. The bear has dense cream-white fur, small rounded ears, a broad realistic muzzle, dark brown eyes, a black nose and an alert, slightly amused natural expression. It must have a true bear head and fur-covered paws, not a human face, mascot suit or teddy toy. Keep the same mustard-yellow technical parka, charcoal hiking trousers, brown hiking boots, dark forest-green backpack, rust-colored gloves and bright-red thermos, resized and fitted naturally to the bear's anatomy. Preserve all colors and object positions. Transform the late-autumn forest into a deep European winter forest while preserving the same tree layout, terrain, fallen-log geometry, creek position and background depth. Cover branches, ferns, moss and the log with fresh powder snow and crystalline frost. Replace amber leaves with snow-coated bare branches and dark evergreen accents. Partially freeze the creek while retaining reflective open-water sections. Add fine falling snow, faint breath vapor and soft mist. Use cool diffused winter daylight with a restrained warm sun shaft from the same direction as the source. Render realistic snow bounce and detailed fur, fabric, bark and ice. The result must clearly read as the same photograph after precise character and seasonal editing. Constraints: exactly one white bear; no human remains; no Asian or East Asian motifs; no second animal; no extra limbs, paws, boots, thermoses or backpacks; no text, logo, watermark, border or UI; no cartoon, plush toy, costume, illustration or plastic CGI appearance.
